CAR-COUPLING.

Specification of Letters Patent.

Patented June 22, 1915.

Application filed February 5, 1913, Serial No. 746,257. Renewed May 20,1915. Serial No. 29,434.

To all whom it may concern Be it known that I, ARTHUR J. BAZELEY, acitizen of the United States, residing at Cleveland, Cuyahogacounty,Ohio, have invented new and useful Improvements in Car-Couplers, ofwhich the following is a specification, reference being had to theaccompanying drawings, in" which Figure 1 is a plan of a coupler showingthe application of my improvements thereto; Fig. 2 is an elevationthereof, and Fig. 3 is a section on line III-III of Fig. 1; Figs: 4 and5 are detailsof the coupler knuckle and one of the coupler earsrespectively.

My invention relates to car couplers and consists in providingvertically extending projections on the knuckle adjacent to the hub.which on one side provide bearings against the outer faces of thecoupler ears and on the other form part of the contour -of the innerface of the knuckle, so that in bufiing the nose of the opposing couplerwill strike the said bearing instead of the coupler ears and the forceof the bufling blow will thus be utilized to the fullest extentthroughout the closing movement of the knuckle up to the moment when thelock drops and the knuckle is locked. and so that the pivot pin may berelieved of strain.

When opposing couplers of ordinary construction come together on astraight track there is ordinarily no difficulty about coupling. butwhen the couplers approach each other at an angleas in coupling on acurvethere is frequently great difficulty in making them couple, andcoupling is achieved only after a number of attempts in which the carsare brought together with considerable force and with resultingdetriment to the equipment. In such instances the trouble in coupling isusually due to the fact that the knuckle of the opposing coupler strikesthe guard arm of the coupler and is thereby driven transversely by theincline of the guard arm so that the nose of the opposing coupler willjam against the coupler cars. which are relatively immovable, and theimpulse imparted to the knuckle by the opposing coupler is lost towardthe end of the closing movement. This difficulty is obviated by myimproved construction. which permits the knuckles of opposing couplersto come together without the impact of the bufling blow being taken upby the coupler ears before the knuckle or knuckles have reached lockingposition.

Referring to the drawings (in which I have shown a coupler of the typedescribed and claimed in my co-pending application, Serial No. 7 36,889,filed December 16. 1912), A indicates the coupler-head, B the knuckleand C the knuckle-pin. The knuckle B has vertically-extendingprojections 2 on the forward side of the knuckle hub 3. The projections2 have continuous bearings 4 under bufling stresses against the ears 5of the coupler-head, and these bearings are carried clear around to therear of the pivot pin to the point 6 and extend tangentially theretofrom the coupler ears and are engaged by correspondingverticallv-disposed bearings7 on the coupler ears 5. The projections 2at the point 8 form part of the continuous bearing wall 9 on the knuckleadjacent the hub 3 by reason .of the fact that the coupler ears 5 havebeen cut away and are of smaller diameter than is the case with theordinary coupler. The cutting away of the coupler ears 5 has been foundfeasible by reason of the fact that in this form of coupler the knuckleis designed to transmit bufiing and draft stresses directly to thecoupler-head. and the coupler-ears and the pivot-pin may accordingly beweakened without detriment to the coupler. It will thus be seen that inbuffing, as the nose 10 of the opposing coupler strikes the continuouswall 9 of the knuckle B at or near the point 8, it will have a rollingaction upon the knuckle at this point and weilldrive it into closedposition in such manner that the impulse given the knuckle B willcontinue until the lock drops into closed position. I A furtheradvantage with this form of coupler is that the knuckle B will have acontinuous socket bearing inner face of the knuckle and extendingtending rearwardly therefrom to relieve the from t'hgl outfer siie ofsaid.1 ears arounfil the pivot pin from lateral pressure.
